Hi All, I'm trying to mix HQL and SQl in the same query. Like using "from ObjectA obj, TABLE_B tbl where obj.someProp = tbl.COLUMN" because my client will need to modify the query, and learning HQL or mapping unmapped tables is out of the question :( If not hibernate, does somebody knows another ORM tool that can accept this? another ...

I will be implementing a feature to update an id in a table after Hibernate does my deletes. But I want to get some feedback on which approach is better.
